Move over, Greenwich Village — Park Slope is now home to the city’s largest historic district.

The city’s Landmarks Preservation Commission yesterday extended the Park Slope Historic District to 2,575 contiguous Brooklyn buildings by adding another 600 19th- and early 20th-century structures to its lineup.

“I am so excited,” said Councilman Brad Lander (D-Brooklyn), who represents the trendy stroller-and-brownstone-laden community, upon learning that Park Slope had surpassed the 2,315-building historic district in The Village.

“I think this recognizes what a great neighborhood Park Slope really is,” he said.

And if the Park Slope Civic Council — which pushed for the expansion — has its way, the historic district will more than double its size by adding on another 3,000 buildings over the next decade.

That includes an 800-building section in the neighborhood’s north side closest to the under-construction Barclays Center, which the civic group especially wants to protect from overzealous developers trying to prosper off the future home of the NBA’s Nets.

The designated buildings in the South Slope lie roughly between Seventh and 15th streets from Seventh to Eighth avenues, and between 14th and 16th streets from Prospect Park West to Eighth Avenue.

Much of the expanded district is filled with tree-lined brownstone blocks, as well as the former Ansonia Clock Works factory on Seventh Avenue — once the world’s largest clock manufacturer — and the homes once inhabited by its employees.

It connects to the existing historic district, an exclusive stretch of townhouses covering more than 30 blocks adjacent to the western side of Prospect Park.

“The extension retains a remarkable degree of cohesion because of its architectural integrity and diversity of 19th and early 20th-century architectural styles,” said Robert Tierney, the commission’s chairman. “These extraordinary characteristics set it apart from every other neighborhood in New York City, giving it a special sense of place.”

Peter Bray, of the Park Slope Civic Council, said the group is lobbying to add another 3,000 buildings to the district over the next decade. They would run from Fifth to Seventh avenues between Flatbush Avenue and 15th Street.

The council has already asked the Landmarks Preservation Commission to consider adding the buildings closest to Barclays Center.

Bray said the district’s newly approved extension not only “celebrates a storied part of the city’s industrial past, but the sensitive adaptive reuse of the factory complex and its contribution towards the vitality and historic character of the area.”
